MEMOIR OF THE LATE DR THOMAS CHARLES HOPE. 423 
time after the beginning of this century, regularly took his share of the duties of 
Clinical Professor of Medicine. 
Dr Biack, who was always of a most delicate constitution, did not feel him- 
self able to lecture after the session of 1796-97 ; but the life of this truly great 
philosopher and most accomplished teacher, was protracted to the 14th of 
November 1799. On his death Dr Hore became the sole Professor of Chemistry 
in our University. ; 
It was in the Session of 1798-99, that the writer of this memoir first became 
Dr Hore’s pupil ; and he remembers, with gratitude, that it was from the clear and 
able prelections, and most happy experimental illustrations of the leading principles 
of the science by Professor Horr, he imbibed that predilection for chemical pur- 
suits, which long formed his chief relaxation from the severer duties of his pro- 
fessional life ; and which, he hopes, will continue to afford interest and amusement 
to his declining years. 
I may here remark, that Dr Horr had become, from the variety and excellence 
of his illustrations, and dexterity in chemical manipulations, the most popular 
teacher of the science that had ever appeared in Great Britain. Not only was 
his lecture-room crowded with medical students from every part of the British 
dominions, but numerous foreigners resorted to Edinburgh, and became his pupils. 
Many of our nobility at that time were among his students. During one of the 
winters that I attended his class, among my fellow-students were the late Earl 
of LAUDERDALE, the present Earl (then Lord Mairuanp), Lord Sempiuy, and 
the late Lord Asupurron. The large class-room was filled to overflowing ; 
and he who was not there before the commencement of the lecture had no 
chance of a seat. 
The rage for chemistry continued for several years; and certainly no chemist 
ever had larger audiences than Dr Horr. I find that the average number of chemical 
pupils here, during the six years preceding Dr Hore’s appointment as Dr Biack’s 
assistant and successor, was 225. When I attended him in the end of the last 
century and beginning of this, his annual pupils were above 400; in 1813 they had 
risen to 500, and in 1827 they had actually amounted to 575. 
While Hore lectured at Glasgow, the total number of his pupils amounted to 
about 300. After his removal to Edinburgh, his chemical lectures were attended 
by 15,500 persons, and the number of tickets issued for his chemical class was no 
less than 16,800. 
His reputation as a lecturer induced a number of the Faculty of Advocates 
to request him to give a summer course of chemistry in 1800; which was also 
attended by many gentlemen engaged in other pursuits. 
-I shall now offer some remarks on the original investigations in which Dr 
Hore at different times engaged, after his paper on Strontites. 
It is well known that Boye, Mariorre, and other philosophers, ascertained
